Frequently Asked Questions

Wet Pour Rubber

What is Wet Pour Rubber?

A Rubber Wetpour system is a porous, poured in place surface developed for a range of applications to provide maximum safety and play value.  It is used on a variety of different applications, such as playgrounds, schools, commercial, domestic and sporting surfaces.  Using the latest in rubber technology, Rubber Wetpour consists of rubber granules or shred bound with a polyurethane resin to form a continuous, seamless surface.  As the product is wet poured in situ, it can easily be installed in difficult areas such as around existing playground equipment, tree roots, pathways etc. This surface does not need a flat area for installation.  It can simply follow the gradient of the land.

Can you Install Custom Designs?

Surfacing Contractors Australia can install bespoke designs. All unique designs must be priced accordingly and individually as every layer of detail will result in additional hours of work. Surfacing Contractors Australia can provide a number of pre-fabricated designs. Please enquire for further details.

Why choose Wet Pour Rubber?

Our wet pour rubber systems are durable, versatile and resilient. When used as an impact attenuation system (softfall) in a play space, it is a permanent fixture that will not erode like loose fill alternatives such as back chip or sand. It is also more cost effective over it effective life span, as the constant maintenance and topping up associated with loose fill products is eliminated.

Is Wet Pour Rubber environmentally friendly?

Our black SBR and Precoat SBR rubber ranges, are all manufactured by shredding and granulating used car tyres. This upcycling process effectively eliminates huge quantities of landfill, making it very environmentally friendly.

Benefits: Why Wetpour Pour?

COST EFFECTIVE

When compared with loose fill alternatives such as bark chip softfall, wet pour rubber results in significant cost savings over the long term. Wet pour rubber allows the elimination of continual topping up and ongoing maintenance which depending on the size and activity level of your playground, will be a serious cost saving. As most wet pour rubber surfaces have a n expected life span of between 10 and 15 years before the need of re-surfacing, the choice becomes obvious.

PERMANENT, IN PLACE IMPACT ATTENUATION

The reality with loose fill alternatives is that they do disperse and erode from key fall areas through use. Without constantly maintaining the depth of your loose softfall, you are leaving yourself open to the risk of an injury, which can become a legal problem.

NO CONTAMINANTS

As a poured in place system, most contaminants and foreign objects that enter your playspace will be easily identifiable. This is not the case with loose fill softfall, where unpleasant items such as syringes, general rubbish and faecal matter can easily be concealed.

INSTALLATION BY QUALIFIED APPLICATORS

Our team of experienced applicators will endure the highest quality wet pour rubber surface is provided. Our surfaces are installed in a range of different thicknesses depending on fall height, durability requirements and other application particulars.

What Wet Pour Rubber systems are available?

There are two main wet pour systems available:

  • Wear layer
  • Bi-laminate

Single layer systems consist of a 20mm coating of 1mm-3mm SBR, Pre-coat SBR or EPDM rubber bound with a single part polyurethane. They are generally used in playground surfaces for areas where fall height for the particular equipment is under 500mm. wear layer surfaces are also used for driveway and veranda coatings, walkways, courtyards etc.

Bi-laminate systems are composed of an underlay of 8mm-10mm SBR laid at varying thicknesses to suit its purpose. It is then sealed with a 15mm coating of 1mm-3mm SBR, Pre-coat SBR or EPDM rubber bound with a single part polyurethane. Bi-laminate systems are generally used in playgrounds under equipment which have fall height requirements ranging between 500mm and 3000mm. they are also used as a flexible pavement at tree surrounds

The thickness of the base layer of rubber is determined by the safe free fall height required.  Many playground equipment manufacturers will specify this however, based on our years of expertise in this field, this requirement can be calculated by us on their behalf.

Our safety surfacing systems have been independently tested to be compliant with Australian Standard AS422:1996.  We continually update compliance with the necessary standards and will issue compliance certificates for our work.

Life span?

A wet pour rubber surface installed by Surfacing Contractors Australia will generally last between 10-15 years if maintained in accordance with our care and use policy.

What is the best sub base for Wet Pour Rubber?

A well stabilised surface of at least 100mm thick road base is suitable. Concrete and bitumen sub bases generally result in a longer lasting product and reduce the chance of ground movement; however, they also add increased cost to the project when compared to installing directly on a rubble sub base.

Does Wet Pour Rubber require any maintenance?

There is some minimal maintenance required to keep your wet pour rubber surface in top condition. Regular sweeping or blowing down of the surface to remove debris such as leaves, sand, excess rubber granules etc. is essential. Power washing of the surface may also be required on an annual or bi-annual basis if debris build up becomes too great.

What is fall height?

The Free Height of Fall (FHOF) is the distance a child could fall from the item of play equipment to the under surfacing.  Every play item will have an individual FHOF that is determined by the manufacturer in accordance with the Playground Standard, and the softfall surfacing must be designed to cater for this fall height at a minimum. all installers must have their own systems independently certified. It is worth noting that these standards are designed to reduce the risk of injury and not to eliminate it completely.

What is the difference between EPDM and Precoat?

EPDM is a completely synthetic product, manufactured from virgin materials. It’s colour is though the entirety of the granule, so that if you were to cut a granule in half, you would still see the colour on the inside. The colour of EPDM is far bolder, and although the product is still susceptible to some variance and fade from UV, the wearing of the colour is very limited and it is much more durable.

PRECOAT is an upcycled product, taking used car tyres that would otherwise end up in landfill and granulating them. They granules are then colour coated in factory. over time, and with more use, the colour will wear off the granule. It is a more environmentally friendly and cost-effective product however.

Synthetic Grass

Can synthetic grass be used for my playground surface?

Surfacing Contractors Australia have a range of synthetic grass impact systems ideal for installation under playgrounds or in childcare centres where portable equipment is used. All of our synthetic grass impact systems area laid on a wet pour rubber sub base at varying thicknesses and ratios to ensure the highest quality product.

What is the life span of synthetic grass?

All product life spans will depend on the purpose of the product and the amount of use it receives. You should be expecting to see between 10-15 years of use of out your synthetic grass, if maintenance as described in the products care and use document is maintained.

What infill materials is available for synthetic grass?

There are a number of infill materials available for your synthetic grass project:

  • Granulated SBR Rubber

SBR rubber is, along with sand, the most widely used infill material for synthetic grass. The reason for this being its cost effectiveness and its resilience over a range of temperature and environmental conditions. Its weaknesses are that it is only available in black, and is not as elastic or resilient as EPDM.

  • Silica sand

silica sand is one of the original infill materials. It is non-toxic, and can be used in conjunction with other infill materials. As compared to other infills, it is also a cheaper product.

  • Organic matter, cork or coconut husk

Organic infills are environmentally friendly products, as they can be recycled back into the environment as the end of their lifecycle. The issue with organics is that they can experience high mold growth if not properly maintained. The maintenance requirement is significantly greater than non-organic infills. Topping up requirements are also greater.

  • EPDM Rubber

A completely synthetic rubber product made from virgin materials, EPDM is a polymer elastomer with high elasticity and proven not to deform in high weather conditions. A vast range of colours area available, and will add an extra bounce to your sports or play surface.

  • Nike Grind

Nike Grind is made from recycling athletics shoes once they have come to the end of their wearable life. As a 100 percent recycled product, it is very environmentally friendly, and all recycled shoes that go into Nike grind meet or exceed the restricted substance standards set for wholesale consumer goods. As it is a blend of whatever shoes are collected, there are no choices of colour, simply a medley. This may not be to everyone’s taste.

  • TPE

TPE (Thermo Plastic Elastomer) is a long lasting, non-toxic and heavy metal free infill product available in a variety of colours. The extruded plastic pellets are typically uniform in size, and are well used as a topping layer to help encapsulate organic softfall such as sand. An expensive product, do not be mislead by cheaper offerings, as quality can vary greatly depending on what virgin materials and fillers are used in the manufacturing process.

Benefits of Synthetic Grass?

Reduced Costs

as a synthetic product, you will not need to spend the money you would have to on a natural turf surface with watering, top dressing, fertilizing, aerating etc. This can amount to a sizable cost saving over its lifespan.

Low Maintenance

Maintenance is minimal when compared to natural turf. You surface may require occasional topping up of its infill (every 1-3 years depending on the amount of use it receives). It is recommended to remove foreign matter such as leaves, other plant life, dirt etc. so as to limit the chance of organic matter building up in and under the surface and to keep it clean. 

Aesthetically Pleasing All Tear Round

No longer will your grass die and become decrepit looking. The quality of our synthetic grass products these days create lush and realistic looking turf areas all year round.

Coolplus Creating Grass 30 Percent Cooler

Synthetic Grass has always become warm in the Australian Summer. We now have products using APT Coolplus technology that uses a PE yarn with inbuilt IR Reflective technology and entanglement technology, creating great aesthetics, softness and above all reduced heat and increased durability.

How long will my acrylic surface last?

The average life span of your acrylic surface is 8—12 years. Acrylic systems are re-coat able, to allow for extended years of use at less cost than the initial construction outlay.

What maintenance is required for my acrylic court?

Minimal, but regular maintenance is required to ensure the quality of appearance and playability of your acrylic surface. Sweeping off of debris with a bristle broom or blower and washing down with potable water on a weekly basis is advised. If you court is endangered by contaminants such as oil/grease, animal droppings or acidic food/drink, it is necessary to remove immediately with high pressure water and a water detergent solution. For further specific details for maintaining you court please refer to our care and usage document for acrylic courts which can be requested.

How long will my synthetic grass surface last?

The average lifespan of a synthetic grass, sand filled tennis court is approximately 7-14 years. This is dependent on whether the required maintenance is upkept, surrounding tree and soil conditions and quality of synthetic grass chosen.

Tennis court crack repairs are undertaken by grinding out a V profile in the crack using an angle grinder. We then fill the crack with an appropriate filler, troweling flush and smooth with surrounding surface. For larger cracks, a fiberglass mesh sheet is fixed over the crack to bridge it. We then apply 1 – 2 coats of acrylic resurfacer to the crack and finally 2 colour coats. In between coats we will send back the edges to create a smooth playing surface.

How long do crack repairs last?

Unfortunately, no warranty can be provided on our crack repairs. Surfacing Contractors Australia cannot guarantee cracking of the paint surface through bitumen will not occur. This is due to several factors outside of Surfacing Contractors Australia’s control such as sub-base design, ground movement, nearby trees, bitumen design etc.  We provide warranty for our paint products and labour, however there is no warranty valid on damage/cracking to Laykold surface caused by bitumen cracking. The majority of surfaces that have received crack repair treatment have seen a minimum of 5 years before any hairline cracking has returned.

What size is an average tennis court?

Your standard tennis court is 23.77m long, 8.23m wide inside the singles lines and 10.97 wide inside the doubles lines.
